Mother Teresa said:
It is never too small. We are so small we look at things in a small way. But God, being Almighty, sees everything great. Therefore, even if you write a letter for a blind man or you just go and sit and listen, or you take the mail for him, or you visit somebody or bring a flower to somebody–small things–or wash clothes for somebody or clean the house. Very humble work that is where you and I must be. For there are many people who can do big things. But there are very few people who will do the small things.
